Leg strength. Equal or unequal

[ushills]

IMO imbalance is normal, the right hand side of my upper body is bigger than the left due to being right-handed.

My right thigh also used to be bigger due to my riding style, I brought some rollers that encourage an equal push on each pedal stroke and now that has affected my road riding style my thighs are equal. My lower left calf still has a more pronounced curve that my right and my physio calls me wonky, but that's the result of genetics.

My average power is around 47% left leg, 53% right leg (measured using Garmin Vectors), though the imbalance is greater at lower powers. Unsurprising given I broke my femur last May, but the left leg is slowly creeping up to parity with the right (was around 40%:60% in January).
